Specification forming part of Letters Patent No. 94,654, dated September7, 1869; patented in England November 5, 1868.

To all whom it may concern.-

Be it known that LJOSEPH F. SARGENT, of Melrose, inthe county ofMiddlesex and State of Massachusetts, have invented Improvements inMachines for Nailing and Peg ging Boots and Shoes; and I do herebydeclare that the following, taken in connection with the drawings whichaccompany wild form part of this specification, is a description of myinvention sutficient to enable those skilled in the art to practice it.Y

The invention relates, particularly, to some of the details ofconstruction of that class of machines for uniting soles of boots andshoes to the uppers in which the fastenings are cut from a continuousscrew-threaded wire, though some of the improvements are alikeapplicable to common pegging-machines in which the pegs are cut fromstrips or ribbons of wood, (this being particularly the case as relatestothe jack or shoe-supporting mechanism,) one branch of the inventionhaving particular reference to and consisting in the peculiarconstruction and arrangement of the jack mechanism, while another parthas reference to and, consists in the peculiar construction andarrangement of the wire feeding and cutting mechanism.

The drawings represent a machine embodying my improvements. v

A shows the machine in front elevation. B

is a view of one side of the'machine. G is a side view of the oppositeside of the head. D is a vertical section on the line a: w,,lookingtoward the rear of the machine.

a denotes the post for supporting the head I), which carries theshoe-feedin g, wire-feeding, and wire-cutting mechanism. 0 is thedrivingshaft; 6?, the swing-plate at the, front of the head, oscillatingmovement of which plate imparts the intermittent teed-movement to the shoe, to bring it into position to receive successive pegs or nails, theplate being hung on a pin, 6, and carrying a feed-foot, f, and havin gits lateral or vibratory movement imparted to it by a rocker-lever, g,apin projecting from 'one arm of the lever into a cam-groove in acam-wheel, h,on the shaft 0, and a pinprojecting from the oppositelever-arm, entering a slot in the back of the swing-plate, this last pinbeing adjustable in a vertical slot in the lever-arm, so that by settingit higher or lower the spacing of the nails may be adjusted as may bedesirable. v v

The feed-foot (which may have a roughened surface, or may carry an awlor a feed-tooth) is fixed to the lower end of the bar. which slidesvertically in the swing-plate, vertical movements are imparted to thefeed-foot by a cam-groove in a cam-wheel, i, on the shaft 0, acting upona pin projectingfroin the slidebar into the groove.

k denotes the peg-tube foot, this foot containing the tube, into whichthe end of the wi're'is fed or transferred, and through which it isforced by the driver linto the sole. Instead of making this footmovable, as in other machines, to transfer the contact of the sole fromthe feed-foot to it, in order that the feedfoot may move back afterhaving fed the shoe, this foot is made stationary, and its lower endacts as a detainer to the shoe, while the feedt'oot swings back after.having fed forward the shoe, the feed-foot first descending against theshoe, (which, by descent of the foot, is

carried away from the detainer or peg-tube foot,) then moving toward andup against the peg-tube foot, carrying the shoe laterally with it, thenrising so that its lower end is brought slightly'above thedetainer-ibot, letting the I shoe up against the detainer-foot, andleaving the shoe against such foot, (the shoe being pressed up by theweighted jack-lever,.) and thenswinging back to its normal position,

leaving the shoe detained against the peg-tube foot, the construction,arrangement, and operation of this shoe-feeding mechanism (except asregards the stationary peg-tube foot) and the mechanism for actuatingthe driver being the same, or substantially the'same, as may be seen inother pegging-machines made and patented by me, thepeg-driver l beingfastened to a driver-bar, m, driven down by a spring, 11-, the bar beinglifted byLa pin projecting from the canrwheel z, acting upon an arm onthe rear face of the bar, andv being thrown down by the spring whenreleased from the pin.

ATENT FFIGE.

The wire being placed on a suitable reel or spool, its end is passeddown through a tube made by two grooves in the adjacent faces of thehead a and a plate, 0, this tube conduct ing the wire between twofeed-wheels, p q,'one

and belowthe feed-wheels leads into a groove.

or to a shoulder, t, on a swing-plate or carrier,- a, on the end of arocker-shaft, '1), there being just above this carrier a stationarycutter, w, and a movable cutter, av,-between which cutters the wirepasses from'the tube .9. The shoulder' t, or the groove made therebybetween the carrier u and an outer plate, 3 terminates at the top of thetube in the peg-tube foot.

The movable cutter as is made circular in form, and 'reciprocatesthrough the arc of a circle, it being confined by a screw-plate,-,z, toan arm on the end of a tubular rocker-shaft or quill, a surrounding therocker-shaft e, The shaft a runs through the head b, and has on its rearend an arm, b in which is a slot, 0 having an incline, d between i, twostraight parts, as seen at D. Through this slot projects a pin, 0 from aslide-bar, which is moved up. and down by an eccentric, g and link k Therocker-shaft t, which carries the shoulder-plate u,-passes throughthe'cuttershaft, and hason its rear end an arm, 1?, having aslot, k,through which the pin 6 also extends, this slot also having an incline,I, as seen at 1);

Whenthebar f? descends, the pin strikes the incline d of thecutter-shaftarm first, and:

moves up the cutter a little in advance of the movement of the arm i andshoulder-plate or carrier 11-. The forwardrotative movement of thecutter brings its. cutting-edge against the wire, pressing the wire,against the stationary-cutter, and severing the wire at this, point.

The end thus severed falls against the shoul der t, and as the pin 0farther descends it passes into the lower and now vertical part ofthe-slot 0 leaving the cutter-shaft at rest,

while such farther descent of the pin, acting on 'the; incline l of thearmt' throws forward the carrier-plate 2i, and brings the wire restingagainst the shoulder t into upright position,

in which position the shoulder of the carrier.

makes, with a stationary shoulder in the plate 5: a vertical tube, fromwhich the severed nail drops down into the stationary tube of the peg- 7tube foot, the driver being up, bringin git into position tobe driveninto the shoe by and at the next descent: of the driver.

When the bar f ri ses, the cutter and th'e I carrier-plate are carriedback to their normal position,.as-will be readilyunderstood, for thenext feed-movement of thewire, the movement of the feed-shaft rbeingproduced by mechanism, as follows: The shaft 1' carries aratchetwheeh'y, withwhich engages a spring-pawl, x hnn g on one arm of arocker-lever, m fnlcrumed on the shaft 9", the end of the other armbeing connected to an eccentric, 12 on the shaft 0 by a link, g As thedriver, after drivin g the nail, next risesthe pawl is thrown forward bythe eccentric n, imparting rotative movement to the Shil fbfifld itsfeed-wheel, and feeding down the wireto an extent equal to the length ofthe nail to be driven, the cutterarm and carrier-plate being drawn, backto allow the wire to pass freely by them. The feed-movement of the wireis finished during the first part of the upward movement of the driver,the cutter being thrown forward to cut the wire, and the shoulder-plateforward to transfer the severed nail into the peg-driver tube before theupward movement of the driver is completed, or while the driver is atits highest point.

As the different; portions of a sole vary in thickness, it is necessarythat the nails correspondingly vary in length, and as the hands of theoperator are engaged in guiding the shoe, and as itisdesirable that thechange from long to short nails and from short to long nails in goinginto. and from the shank should be effected without stopping themachine, it

is requisite that provision should bemade for effecting change in theextent of rotative movement of the feed shaft ratchet by the foot of theoperator while the nailing operation is progressin g.

In Letters Patent No. 7 7 ,104, granted to me,

a provision is made for producing variable feed of the ratchet-wheel byhand by means of a movable shell partially covering the ratchet-wheel,such shell being moved forward or-back'gunder the path of the pawl, soas to cause the pawl to traverse a greater or less extent in contactwith theratchet-teeth'. In

the presentfm achine, instead of such shell, 1 I

use a circular guard, 2, whose edge is concentricwith theratchet-teeth,(but projects a'little beyond them,) except in a small 'part, where theedge is cut away or comes below the teeth.

The guard plate or disk turns on the feedshaft, andby rotating it moreor less its projecting edge is throwninto the path of moveinentof thepawl-tooth, this tooth-being of a ,width greater than the thickness ofthe ratchet,

and extending over and resting upon the edge of the guard projectingbeyond the ratchet; teeth. The guard is moved by'a pin projecting from-acrank-arm, 0 of a shaft, 9 in line with the feed-shaft, and at the outerend of this shaft 1) is an arm, g connected bya rod,

W, with a treadle or foot-lever, 8 so that by tipping the't-readle up ordown the projecting edge oftheguard is thrown 'moreor less'into the pathof the pawl, thereby causing more or less movement of the ratchet--wheel and a greater or less extent of feed of the wire. In anyspecific style of shoes being pegged. there is, of course, a uniformityof thickness of sole in the corresponding parts of difierent shoes,'andas long nails of uniform, or nearly uniform, length are required allalong the main sole, and short nails'of uniform length a're'required inthe shank, I make the extent of movement of the guard adjustable, sothat no nails out can exceed. the required length for the long nails,nor be cut shorter than the nails requiredin the shank. To effect thistwo'ears, 10 project fiOlll the opposite sides of, the shaft 19 througheach of which an adjusting-screw, t extends, theend of each screwstriking against thehead a, when'the shaft is turned in one or theopposite direction, and thereby stopping further movement of theratchet-guard in such direction, and determinin g the greatest lengthand the shortest length of nails that can be cut from the'wirewhile themachine is in operation, the change from. short to long and from long toshort nails bein g instantly or. gradually made by the operator duringthe operation of the machine.

Each wire-cutter is made with a beveled or chisel. edge, the lowersurface of the cutters being straight to the cutting-edge, and the edgebeveling back to the top surface, so that the top of the severed nail iscut square, whilethe end of the wire above, forming the point of thenext nail, is pressed into an awl-point form. r v

The wire may be cut by two movable cutters, moving toward each other andmeeting at the center of the wire, or the one movable cutter may actagainst a fiat-surfaced bed. The swin g-carrier which takes the cut nailmay be made in one piece with the peg-tube foot, as seen at E, the footthen swinging from inclined to vertical position to bring the tube underthe driver; or the carrier may be made in one piece with the plate y, asseen at F, the plate, of course, being then movable, and the wire beingfed from the feed-wheels down into a tuberunning through theswing-piece. The specific construction show-n, sider to be the mostpractical.

The shoe to be nailed is mounted upon a jack mechanism, as follows: (t-denotes the jack-supporting upright, pivoted to the front end of aweighted lever, W, by a swivel-foot,

0 said foot swiveling freely'toward and away from the post a. upon apin, d connecting it to the-lever and the upright a swiveling loosely(upon the pin by which it is hung to the swivel-foot) in a lateraldirection, these two movements not only permitting the jack to be movedentirely away from the pegging mechanismto permit ashoe to be placedupon the last or removed therefrom, but also permitting the shoe to befed by the nailing mechanism, as is required, to bring the whole edge ofthe shoe to the action of the naildriver.

To the top of the upright is jointed, bya pin, a the jack-holder)", thisholder hanging pendulously on the pin, and being kept up to the uprightby a lip, g, the extent of its vihowever, I con- .brating movement ineither direction being limited by stops j 'j which stops are madeadjustable, so as to regulate the extent of tip.-

ping movement to thedegree of curvature in the soles or shanks of thestyle of shoes to be pegged or nailed upon the machine. From the holderprojects a spindle, h upon which the jack 0 is mounted, a socket-piece,i on the jack supporting it upon the spindle and permitting freerotative movement of the jack on the spindle. Directly over the spindlethe with the ratchet, outward pressure of the lower end of the armforcing the last against the toe-piecegfi, against which it is detainedby the pawl and ratchet. The two arms m? n form-a handle for one hand ofthe operatorin guiding the shoe being pegged, and another arm, gprojecting'down from the other end of the bar 1 forms a handle for theother hand. In the arm g is a slot, 1' into which projects a pinextending from theend of one arm, 8 of a bent lever, fulcrumed'at t toan extension, 02 from the socket-piece i To the other arm, a of thislever is fixed a spring,

42 looking into a slot in the edge of a lip, 11

on the piece w locking the shoe in stationary position relatively to thesocket-piece.

. So far as the relative arrangement of the parts to which the shoe isdirectly jacked is cbncerned, the jack mechanism doesnot ma 'teriallydifl'er from that shown in my patent No. 44,691. In such patent there isclaimed in a pegging-machine the employment of a jack so constructed ormounted that it can turn or be turned laterally to hold the shoe"properly to the action of the awl throughout its varying lateralcurvature, and the arrangement now shown is embraced by/ such claim.

In the specific construction shown in such patent, however, the jack is,automatically tipped as the variously curved portions of the edge of thesole come under the action of the shoe-feeding and peg-drivin gmechanism by a jointed connection with the pegging-machine standard.Such arrangement requires great skill and strength in the operator tokeep the shoe firmly in position, and the purpose of my presentconstruction is to not only enable the jack to be freely tipped by theoperator, but to cause the shoe to be held steadily in position underthe driver. For this purpose I place the pin upon which the jack turnsup close to the last, as seen in. the drawings, and

arrange the jack-holder to be tipped freely by hand,the tipping bar orholder not being a part of the jack itself, but being tipped by thehandles of the jack, so that this tipping movement, being independent ofthe rotating movements of the jack, leaves the jack equally free tobetipped by hand in all positions into which the shoe is brought underthe driver.

Then the pin upon which thejack-holder tipsis so arranged that when theshank of the sole is pressed up against, the feed and peg-tube foot thepressure swings the bottomof the holder up toward the standard, theholder being held by the stop-pin, and held firmly in the position intowhich it is tipped by the pressure between the lever and the peggingmechanism, (a line drawn from the lever-pin to the: feed-foot passingoutside of the pin on which the jack-holder is hung,) while,.as theshoe' is fed from the shank tor heel, the holder is thrown outwardassoon as the shoe, in being turned, is brought to such position that aline from the feed-foot to the lever-pin W111 pass inside of thejack-holder pin, the changing positions thus assumed by the jack beingthose necessary'to keep the surface being pegged in 'roper positionrelative to the peg-driver for each nail to enter the soleperpendicularly to the surface into which it is driven. Thus theefi'orts of the operator .may be Wholly directed to guiding the shoewithout outlay of strength to keep it in position.

The shoes to be nailed are placed upon metal-bottomed lasts', and theblow of the driver, not only drives the nail, but upsets one or lastacting as an anvil.

I claim both ends of the nail, the metal surface of the 1'. Incombination with the wire=feeding and nail-driving mechanism, a cutterhaving a rotative mofi'mnent to sever the nail, substanthe shoe beinganism,

tially as described, when the cutter is a sep-' arate instrument fromthe wire-feeding and nail-driving mechanism, and acts to sever the nailbefore it is driven.

2. Incombination with such cutter, an in-' dependent vibrating orreciprocatingi carrier, which receives the end of the wire andtransfersfiit, when out, from its inclined position to vertical positionover the peg-driver tube, substantially as described.

3. In combination with the wire-feed mecha mechanism for enabling theextent of feed of the wire to be varied by the foot of the operator,substantially as described, such mechanism being independent of theshoe-supporting mechanism.

4. In combination with the feed-ratchet, the

mechanismfor limiting and adjusting the extent of feed-movement of theratchet, substantially as described. 1 5. In combinat'on with theshoe-feed foot, having up and down, forward, and back movements, asdescribed, the stationary driver-tubc or detainer-foot, substantially asdescribed;

6. The construction and arrangement of the,

jack-supporting mechanism, by which the shoe may not only be tippedfreely by the operator.

'in all directions necessary for its proper pre- 7 sentation, but isheld by the stress of the lever-weight toward its proper position,substantially as described.
